High voltage electrostatic range hood

Abstract

The invention discloses a high voltage electrostatic range hood, which comprise a range hood shell, an air inlet, an air outlet, an exhaust fan, high voltage electrostatic purifying modules, a flow equalizing plate, and a control box. The left end of the range hood shell is provided with the air inlet; the right end of the range hood shell is provided with the air outlet; the air outlet is connected to the exhaust fan; multiple high voltage electrostatic purifying modules are arranged in the range hood shell; the control box is arranged on the range hood shell; the flow equalizing plate is arranged in the air inlet; and the flow equalizing plate is provided with flow equalizing holes, which are all outwards obliquely arranged. The high voltage electrostatic range hood has the advantages that the oil fume particles are more evenly absorbed by the high voltage electrostatic purifying modules, the cleaning period for the high voltage electrostatic purifying modules is prolonged, the highvoltage electrostatic purifying modules do not need to be washed frequently; a discharge needle will not contact with a metal cylinder during the using process, the short circuit is prevented, the operation is stable, the vibration discharging is prevented effectively, the service life of an electric field is prolonged, and the maintenance frequency is reduced.

Description

technical field [0001] The invention belongs to the technical field of range hoods, in particular to a high-voltage electrostatic range hood. Background technique [0002] The electrostatic range hood uses the electrons emitted by the cathode in the high-voltage electric field and the negative ions generated by the electrons colliding with the air molecules to capture the fume particles, charge the fume particles, and then use the effect of the electric field to make the charged fume particles adsorbed by the anode , in order to achieve the purpose of oil fume removal. Because the diameter of electrons is very small, its particle size is many orders of magnitude smaller than that of soot particles. Moreover, the density of electrons in the electric field is very high (up to an order of magnitude of 100 million / cm3), which can be said to be everywhere. The soot particles in the electric field are easily captured by electrons (that is, charged). The charging of the soot part...

Problems solved by technology

However, the flow equalizers of the electrostatic range hoods currently on the market adopt a honeycomb design. This kind of flow equalizers can evenly flow away the smoke drawn in, but the flow equalization effect is not good, and the middle part is often equalized. For a long time, the middle part of the high-voltage electrostatic purification module will absorb more oil fume particles, and the side will absorb less; and the discharge needle is only fixed at one end. When the discharge needle absorbs oil fume When there are many particles, the discharge needle will bend down, and in severe cases, it will touch the metal cylinder and cause a short circuit of the electrostatic range hood
